introduction:
I went into a roastery or an online store… I found a coffee bag with the following written on it:
"Packed with nitrogen gas to preserve flavor."
What does it mean? And is it really different from any other bag?
In this article, we simply explain the difference between regular coffee and nitrogen-enriched coffee, and when it's the best choice for you.
1. What is nitrogen filling?
It is a technique in which nitrogen gas is pumped into the bag before sealing, instead of regular air.
✅ Objective:
- Oxygen expulsion
- Reducing oxidation
- Preserving aromatic oils and flavors
2. What is the difference between nitrogen and normal air?
- Air contains oxygen = accelerates flavor spoilage
- Nitrogen is an inert gas = it reacts with volatile oils
🎯 The result? The coffee retains its flavor longer (especially during shipping or storage).
3. When do you need nitrogen-coated coffee?
- If you buy in bulk and store them
- If you order from distant roasters
- If the roasting date is not very close
❌ If you consume the coffee within two weeks of roasting? You probably need it.
4. Does it really make a difference in taste?
✅ Yes, if:
- I opened the coffee after a long time
- Or the bag was exposed to heat during transportation
- ❌ But what gives you a "stronger flavor", just keeps it longer.
✅ Conclusion:
Nitrogen filling does not change the taste of the coffee... but it protects it from change.
If you are someone who buys in bulk, or orders from far away, this option will be useful for you.
